IMPROVEMENT IN INVALID-CHAIRS.

Specification forming part of Letters Patent No. 210,125, dated November19, 1878; application filed February 21, 1878.

To all whom it may concern:

Be it known that I, ANTHONY Isms, of the city of Lancaster, in thecounty of Lancaster and State of Pennsylvania, have invented certainImprovements in lnvalid or Surgical Chairs, of which the followingis aspecification:

These improvements relate to a class of reclinin g or invalid chairs inwhich leg and foot supports are hinged to the seat, and the seat to theback, so that they are capable of assuming and retaining any requiredposition, from the erect to the prone, by means of sustaining devicesconsisting of racks and screws.

The improvements consist in additional appliances, and in thearrangement of the adjustable parts with the view to meet contingenciesarising, to simplify the operation, and give a more extended range ofusefulness.

The accompanying drawings, with the letters of reference marked thereonand a brief description, will enable those skilled in the art to makeand use my improvements.

Figure 1 is a perspective view of the chair, to show its severalnovelties in place; Fig. 2, a perspective view of the side rack and theback-brace, seat, and back of the chair. Fig. 3 shows foldingtabletsmounted on a rod which connects with the plates in the arm-rest. I alsoshow a portion of the under side of the central foot-rest.

The sides and legs F of the chair, on each side, are formed bygracefully curving ordinary gas-pipe, and are left horizontal centrallyon top to receive a plate, V. This plate is centrally cut in so as tobend over and embrace the pipe F, to which it is secured. The ends 22are allowed to project on a levelplane for holding the board X for beingupholstered, to form the ordinary arm-rest. The two sides of the chairhave the ordinary braces f, also a special stout brace, F F, across therear, partially embracing the legs in a rounded groove, to give thegreater strength wheremost needed.

To facilitate the upholstering I use wooden frames for the seat andback, but attach to the sides and back-frame metal straps A B E, bein glighter and stronger and with the strap A in front I connect a hanger,a, which has play in a joint-piece, 6, connected with the sides of thechair. These hangers are bent inward, and

have the ends below united by a cross bar or on the back, which isconnected by a hingeplatc, D, with the head-plate E. In order tofacilitate the upholstering I use a slotted hookplate, 0, affixed to theside of the chair-frame, and a headed pin in the strap B, so that theback can be detached from the sides and laid down, giving full access tothe rear of the seat and bottom ofthe back, which is very desirable.

The back is adjusted and held in place by a side rack, W, provided witha guard-plate, w, to confine its action, and a headed pin in the seatplate or strap, A, which latter isv in connection with strap B on theback. The rack is held by a pivot-bolt in a lug, y, connected to thestout back-brace F F, as shown in Fig. 2. The foot and leg rest hingedto the front J of the chair-frame diifers in the construction of theadjustable foot-piece, having. a hinged piece, N, and arms M. These armshave aseries of perforations on the under side and a guide-lug, m, oneach outer side. These arms slide in square openings made in a verticalcross piece, l, and rest upon a bottom, L, the pin n entering theperforations in the arms M. The sides K also have slots or grooves forthe lugs or pins m in said arms.

To meet certain cases, in combination with the ordinary central foot andleg support, I also employ independent side supports 0, hinged to J. Thesides of the plates 0 are notched. A hinged foot-pieced; P, is slippedon and under by prolonging the sides P downward at their ends, so thatthese ends extend beneath theplate 0 and look into the notches in thesides K, and are firmly held in place.

Each side support has its own rack Q. In order that the side supportsmay be operated with the central support jointly or separately, I use aturn-plate, q, under the. ends or-sides K. This plate has twoprojections one e11- gages under the plate 0 and the other over it, andby which they are held in connection for the purpose aforesaid.

It is found that tables connected with such chairs are useful, and Iattach a metallic plate,

Y, on the front end of the board X, which plate has a central opening toreceive the end of the bent rod Z, which supports the hinged tablets tT, which, when laid open, form a table 5 when folded down, anupholstered cushion for a front arm rest or support, which is readilydetached and is very simple.

My hinged headpiece turns down orupward, and is held and adjusted by ahinged rack, b d, on the top or head piece, and held in a binding-screw,g, and angle-plate "r, on the back and top of the seat-frame, centrallyaffixed. For a lounge this answers for a head-board to hold a pillow inplace. At the same time, for certain operations, it allows the head tofall back.

It is in these minute changes, devised to meet various complications andobjections made, that my invention consists, and so to arrange andcombine the parts as to meet the demands for more extended usefulness.

The several improvements which I deem novel in their construction, use,and arrangement, in invalid or surgical-operatin g chairs, and desire tosecure, are- 1. An invalid or reclining chair, provided with a centraladjustable foot-rest and two independently-adjustable leg and foot restsone on each side the first named, operating substantially as and for thepurpose set forth.

2. The combination, as set forth, of the armboards X, the perforatedfront plate, Y, the rod Z, and hinged tablets t T, whereby such tabletsmay be used, when extended, as a bookrest or table, and, when folded, asan upholstering for the arms.

3. The combination of the back pivoted in the slot on the back-standardF, the movable seat provided with strap A, the lever 11, pivoted to thefront standard, I, above the seat and the foot-rest pivoted to the frontedge of the seat, and attached by'means of the racks Q to the lever a,as and for the purpose set forth.
